How to replace Uebimiau with Squirrelmail

For those who whish to abandon the /webmail link Uebimiau and replace it with squirrelmail, you can accomplish that by doing the following.

Edit your /etc/httpd/conf/httpd.conf (/etc/httpd/conf/extra/httpd-alias.conf if you're using custombuild)

Change the code

Alias /webmail /var/www/html/webmail/

to the code

Alias /webmail /var/www/html/squirrelmail/

Then restart apache.   This will make all accesses of /webmail point to squirrelmail.
